実験手順

Hydrogen chloride was passed into a solution 110 mg of (2RS, 3S)-3-amino-2-hydroxy-5-methylhexanoic acid in 10 ml of methanol under ice-cooling, and the mixture was stirred overnight. The reaction mixture was evaporated to dryness under reduced pressure to obtain 150 mg of methyl (2RS, 3S)-3-amino-2-hydroxy-5-methylhexanoate hydrochloride as a white powder.
